Co-guiding Net: Achieving Mutual Guidances between Multiple Intent Detection and Slot Filling via Heterogeneous Semantics-Label Graphs. (arXiv:2210.10375v2 [cs.CL] UPDATED)

Recent graph-based models for joint multiple intent detection and slot
filling have obtained promising results through modeling the guidance from the
prediction of intents to the decoding of slot filling. However, existing
methods (1) only model the \textit{unidirectional guidance} from intent to
slot; (2) adopt \textit{homogeneous graphs} to model the interactions between
the slot semantics nodes and intent label nodes, which limit the performance.
In this paper, we propose a novel model termed Co-guiding Net, which implements
a two-stage framework …
